The wacros do default the renderer to Firefly, but you can just go back into the render settings and switch it back to Superfly. You would indeed though probably get better results using Superfly specific reflection/refraction as the wacros cause broken shaders for Superfly, as the dashed connections in the material room show.

I would recommend having a play with ghostship2's Uber shader for P11 (it's free) that allows pretty much any material from one shader. You can read about it (and I believe there is a link to it as well) in this post I would recommend reading the whole thread) in the Poser forum: https://www.renderosity.com/mod/forumpro/?thread_id=2906113&page_number=2
